I don't see how this is a problem at all.  Navigating the "vacuous" structure is as simple as pressing the tab key a few times.  But if you change the mapping convention between files and module names, you need to do it for all tools, not just the compiler.  I imagine all of the following tools would need to know about it:

cabal, hoogle, haddock, happy, alex, hat, hsc2hs

and probably a few more.  The feature seems like a very low power-to-weight ratio, so -1 from me.
